What does the acronym LEO stand for in the context of aviation?

In the context of aviation, the acronym LEO stands for Law Enforcement Officer. This designation is important as it refers to officers who have the authority to enforce laws and regulations regarding aviation security and safety. Such officers play a critical role in ensuring that the aviation environment remains secure, particularly in situations that may involve criminal activity or threats to passenger safety. Their presence at airports and aboard aircraft is essential for maintaining order and addressing any potential incidents effectively.

The other options, while they may represent roles or titles in various sectors, do not align with the specific and recognized meaning of LEO in aviation settings. Hence, understanding that LEO explicitly refers to law enforcement personnel is key to grasping its significance in the aviation industry.
